When good things go bad: a purse-seine in action
Greenpeace is not against purse-seining, which
may surprise some people. Sure it's a big industrial-looking fishing operation,
involving huge nets and catching lots of fish. But that's not always a bad
thing.
If we are to assume we're still going to
catch and eat fish, then purse-seining as a method is probably going to be
something that continues. Purse-seining
involves setting a large circular wall of net around fish, then 'pursing' the
bottom together to capture them. Where purse-seining is best used is with large
single-species schools of fish, that shoal tightly together. Examples like
herring or mackerel
spring to mind. These can be caught relatively 'cleanly' by
purse-seining.
